Claims. (Cl. 167-84) This application is a continuation in partof the'application filed August 3, 1932, Serial No. 627,830, entitled Bandage, and a continuation in part of the application filed August 7, 1933, Se- 5 rial No. 684,120, entitled Antiseptic dressing and a continuation in part of application #648,990, filed December 27, 1932, all said applications being in the name of Edward Fetter.

The invention relates to,the treatment of sores,

9 bruises, cuts and external injuries and the like where the continued application of a healing antiseptic is desirable. For this purpose the invention provides an antiseptic bandage which is particularly eflective in the application of a healing antiseptic to the portion of the body being treated.

In accordance with the practice of the invention in the preferred form, raw rubber which is preferably clean, or which has been washed by the methods known to the rubber art, is masti- 20 cated and mixed with oxyquinoline. The actual mixing of the antiseptic'in and throughout the body of the rubber is of importance. The rubber thus mixed with said healing antiseptic is then rolled or otherwise formed into sheets of the desired width, thickness and length.

The rubber bandage material thus produced.

possesses elastic properties to a considerable degree which are useful in fitting the bandage and keeping it in contact with the injured portion. It is: also self adhesive and preferably moldable to some degree, which self adhesive and moldable properties, as well as the elasticity, are effective in the application of the bandage.

- In the use of the article .of the invention, assuming that a finger is injured so that the skin is broken,. asmall portion of the bandage, is wrapped about the finger and'sealed at all points by merely rubbing with a finger of the other hand and pressing together the contacting edges. If desired, any protuberances due to joining the edges or to excess material can be removed by means of scissors without causing leakage provided the edges of any openings which are left are merely brought in to contact with each other and pressed together. The bandage material thus forms a liquid and gas proof antiseptic covering which protects the injury, the wound being so thoroughly and efiectively protected thatthe injured person may continue with his work immediately. Instead of a. plain sheet material, a porous sheet may be used which provides ventilation but still gives efiective' protection even from liquids. The important feature of the invention resides in the manner of retaining and applying the healing antiseptic which is mixed in the body of the rubberand retained in the rubber when the surface of the same is protected or even under other circumstances at normal room temperatures, and is discharged from the bandage when applied due to the heat of the body so that the antiseptic is gradually released from the rubber and applied continuously to the portion of the body covered by the bandage, giving a continuous treatment of the wound.

It is also of interest that when the antiseptic bandage is enclosed in a transparent container and warmed to a temperature corresponding to the heat of the body, the antiseptic is gradually released and deposited on the sides of the container forming needles which seem to be of crystalline structure and which grow in length as the discharge of the antiseptic continues. Such crystalline needles of the length of onehalf to three-quarters of an inch have been observed under these circumstances.

The bandage prepared as above has proved highly successful in use, the continuous treatment of the wound or sore with antiseptic in this way being very effective.

In addition to oxyquinoline, it is found that other healing an'tiseptics may be used in this way, particularly the one known as hexylresorcinol. This material has been mixed with raw rubber, as above described in connection with oxyquinoline. The material thus mixed is rolled into sheets which have the physical properties previously related, i. e., they are elastic to a degree, though they do not ordinarily have the resiliency of vulcanized rubber. They are also self adhesive and moldable to a greater orless extent and the hexylresorcinol, like the oxyquinoline is retained in the rubber at normal room temperatures or when suitably protected, being discharged by the heat of the body as above described-when the bandage is applied to. the wound, giving a continuous ap-' plication of the antiseptic to the wound.

For commercial distribution the bandage is preferably made in thin sheets which are formed into strips. These rips are rolled up with a protective strip as per or cloth with which a piece of gauze may be included, if desired, These details are no part or the invention. It is further of interest that while the bandage material is self adhesive to a high degree so that when pressed by the fingers it practically becomes welded, it is non adhesive as to the skin and after being applied it can be easily removed at any time without injury to the partially healed wound.

The invention has been described specifically in detail in order that the manner of producing thearticle'and of applying it in use may be fully understood, however, the specific terms herein are used descriptively rather than in a limiting sense, the scope of the invention being defined in the claims.

What is claimed as new and by Letters Patent is:

1. A bandage consisting of unvulcanized rubber which is self adhesive and'moldable, the rubber having mixed therein throughout the body of the material oxyquinoline, in the form of an antiseptic which is solid at normal room temperatures, but gradually vaporized by the heat of the body and discharged from the rubber so that it is continuously, supplied to the skin beneath the bandage when the bandage is in use.

2. A bandage comprising a sheet of self adhesive moldable unvulcanized sheet rubber, the rubber containing oxyquinoline mixed in the body of the rubber and throughout the same, the

I 4 desired to secure oxyquinoline being retained in the rubber when the surface is covered and protected and being discharged by the bandage'due to the heat of the body when the bandage is applied so that the oxyquinoline is supplied continuously to the portion of the body covered by the bandage.

3.'A bandage comprising a sheet of self adhesive moldable unvulcanized rubber containing hexylresorcinol mixed in the body of the rubber aoeaeee and throughout the same, the hexylresorcinol being retained in the rubber when the surface is covered and protected and being discharged by the bandage due to the heat of the body when the bandage is applied so that the hex-' the antiseptic is applied continuously to the portion of the body covered by the bandage.

5. Abandage comprising a sheet of self adhesive unvulcanized rubber having mixed in the body of the rubber and throughout the same a healing agent adapted for external application, which healing agent is adapted to be retained in the rubber when'the surface of the same is covered and protected and is adapted to be discharged therefrom dueto the heat of the body when the bandage is applied so that the healing agent is applied continuously to the por= tion of the body covered by the bandage.
